I figured that it may be possible, if they had the specific condition(s) that caused one to be a midget. She figured it isn't possible because... they're smurfs. She said they were already short so I guess that means they couldn't be any shorter, or some such. I decided to read a little bit on the subject.
Midget is an extremely short person. The term generally describes a person with the medical condition dwarfism. The terms midget and dwarf are often used synonymously, because both terms mean someone who has been short in stature since birth, but they were not originally synonyms.
Well, Smurfs ARE extremely short but only by human standards. By Smurf standards their height is normal. As far as actual Dwarfism though, I'm not sure if they could be born with it. Apparently Dwarfism can be caused by about 200 distinct medical conditions according to wikipedia. I'm not sure if they could acquire any of those, but do they have any such conditions of their own that might cause it?
Webster.com's definitions of the word "Midget" include this one:
a front-engine, single-seat, open-wheel racing car smaller and of less engine displacement than standard cars of the type
That's an interesting one. I've never considered the possibility that the Smurfs are actually small race cars. Obviously they don't look it, but looks can be deceiving. I mean, think about the recent movie The Dark Knight. The Joker? Best, Joker, EVER! If you've seen the movie you know what I'm talking about.
Think about it... Heath Ledger, would you have thought he would have made such a fantastic Joker? I sure wouldn't have. Someone, somewhere had some crazy-awesome vision, let me tell you. I can imagine it went something like this:
Executive: Hmm, who can we get to play the Joker in our new movie?
Someguy: I'm not sure... hmm. I know... penguins...
Executive: What about... penguins?
Someguy: They're birds right? But they can't fly...
Executive: Go on...
Someguy: So, Heath Ledger.
Executive: What? You mean that guy in the gay cowboy movie?
Someguy: Yeah, the guy who played a gay cowboy in that gay cowboy movie.
Executive: Are you mad, sir? Him? As the JOKER?
Someguy: Remember sir, penguins.
Executive: Yeah yeah I know... ok do it.
And you know what? Best Joker EVER! So things are not always as they appear. But, I fear, not being able to examine any REAL smurfs (they are good runners and have a mean fear of needles) we may never actually get to study one and find out for sure.
It may end up being another great unsolved mystery.
